I hadn't really listened to the radio in a long time, but recently started listening to the AAA station in Pittsburgh when my car mp3 player broke (just haven't gotten around to replacing it). It steadily alternates between 90's rock (heavily Nirvana, Pearl Jam, Foo Fighters, etc) or the Lumineers/Mumford/Of Monsters and Men types for anything newer. No room for anything else. It makes for an odd mix. Every weekday they have a thing where people can vote for whether to keep or drop a new song that the station wants to promote, and the DJs often read the texts and tweets they get about them. Whenever a more traditional rock song is debuted, a chorus of texts/tweets will end up being read about how listeners are happy to hear a new song that doesn't have clapping in it. The overall playlist never seems to change though.
